Heat preservation and temperature control organic waste biological drying reactor

Abstract

The invention discloses a heat preservation and temperature control organic waste biological drying reactor which comprises a double-layer closed bin, an air blower, a breather pipe, a heat storage medium circulating system and a solar power generation heating system. The heat storage medium circulating system comprises a heat storage box, an inlet pipe, a circulating pump, an outlet pipe, a first medium flowing pipe and a second medium flowing pipe, wherein the first medium flowing pipe is communicated in parallel and wound around the outer wall face of the inner bin, and the second medium flowing pipe is spirally wound around the inner wall face of the outer bin. The two ends of the first medium flowing pipe and the two ends of the second medium flowing pipe are communicated and switched with the inlet pipe and the outlet pipe through three-way valves correspondingly, and switching of heat absorption and heat release is achieved. One end of the ventilation pipe is connected with the air blower, and the other end penetrates through the heat storage box and extends to the ventilation plate for aeration. According to the reactor, solar energy is stored through combination of two modes of solar cell panel power generation and heat storage medium circulation, energy is provided for the reactor, energy consumption is reduced, temperature regulation and control in different modes day and night can be achieved, the relatively stable environment temperature is maintained, and biological drying is normally started.

Description

technical field [0001] The invention relates to the technical field of organic waste disposal and resource utilization, in particular to a thermal insulation and temperature control organic waste biological drying reactor. Background technique [0002] Organic waste refers to a type of organic matter discarded by people in life and production activities, mainly including agricultural waste (straw, livestock and poultry manure, etc.), urban waste (garden branches and leaves, municipal sludge, kitchen waste, etc.) And industrial waste (sugar residue, distiller's grains, etc.). Since the founding of New China, the total amount of organic waste resources in my country has shown a gradual upward trend, from less than 500 million tons in 1949 to more than 2 billion tons so far, with an astonishing growth rate. Organic waste has a high water content, and if it is not treated in time, it will produce foul-smelling gas, which will affect the production and life of residents. Organi...

AI Technical Summary

Problems solved by technology

[0005] (1) Small-scale reactors have poor thermal insulation effect due to their small volume;

[0006] (2) Existing reactors cannot be used in alpine regions, where the temperature is low and the temperature difference between day and night is large, and it is difficult for microorganisms to grow and reproduce, resulting in the failure of normal start-up of biological drying;

[0007] (3) The biological drying reactor is mainly heated by electric energy, resulting in high energy consumption;

[0008] (4) A large amount of condensed water accumulates at the gas outlet of the biological drying reactor due to the large temperature change, which leads to the backflow of water and is difficult to remove, which greatly affects the efficiency of biological drying
